CLAMPlNG-APPARATUS.

SPECIFICATION forming part of Letters Patent No. 680,859, dated August20, 1901. Application filed November 10,1898, Serial No. 696,072. (Nomodel.)

To 00% whom it vita/y concern.-

Be it known that we, ANTON HAssLER and JOHN T. WATTERS, citizens of theUnited States, and residents of Oakland, county of Alameda, and'State'ofCalifornia, have invented certain new and useful Improvements inClamping Apparatus; and we do hereby declare the following to be a full,clear, and exact description of said invention, such as will enableothers skilled in the art to which it most nearly appertains to make,use, and practice the same.

Our invention relates to improvements in that class of apparatus knownas clampingmachines for doors, sashes, blinds, &c., and for the purposeof this application we will refer hereinafter to a machineparticularlyadapted for door-frames.

While clamping together the various parts of a door-frame the rails,which are supposed to fit at right angles with the styles, are veryoften not properly set, and if clamped in such a way the frame has to betaken apart or cast away, as the case may be.

The object of our invention is to obviate such inconvenience and toprovide simple and ever ready means whereby the rails and styles can beproperly adjusted while clamping the frame.

To this end our invention consists in providing clamping-machines withan adjustable work-seat and clamping-jaws, as will be more fullydescribed hereinafter.

Reference is had to the accompanying drawings, which form part of thefollowing description, in which- Figure 1 represents the top view of anordinary clamping-machine, showing the frame of a door and ourimprovements in position. Fig. 2 is a right end elevation of Fig. 1. 3is a broken isometrical projection taken from dotted line 1 t0 1 of Fig.1 looking in the direction of the arrows. Figs. 4, 5, 6, '7, 8, 9, 10,11, and 12 illustrate various ways of constructing ourinvention and maybe described as follows: Fig. 4 is a top plan view of an ordinaryclamping-machine provided with our invention in modified form. Fig. 5

is a right end elevation of Fig. l. Fig. 6 is a broken isometricalprojection taken from dotted line 2 to 2 of Fig. 4 looking in the di-Fig. 7 is an isometrection of the arrows.

rical projection showing a different position of Fig. 6. Fig. Sis abroken cross-section taken from dotted line 3 to 3 of Fig. 7. Fig. 9 isan end elevation similar to Figs. 2 and 5 of a third form of ourinvention. Fig. 10 is an isometrical broken projection similar to Figs.3 and 6. Fig. 11 is an isometrical projection of one of the bearings bywhich the work-seat can be adjusted, and Fig. 12 is a cross-elevationsimilar to Fig. 10.

Similar letters refer throughout the drawings.

In the class of machines to which our improvements relate it is usual toprovide a suitable frame A, the stationary rail B, and the movable andadjustable rail 0, both horizontally mounted upon the frame, thewormscrews D, provided with suitable cranks a, by which the rail 0 ismoved, and the workseats E E, provided with parallel jaws orclamping-backs F F, mounted upon the rails B and C. To provide suchmachine with our improvements, referring now to Figs. 1 to 3,exclusively, we place between the bearingfaces of the work-seat E andthe rail 0 antifriction-balls Z), upon which the work-seat is supported,so that the latter can freely move longitudinally and set the door framein proper position while clamping the same. The balls I) are preferablyseated in suitable grooves cut for that purpose upon the upperbearing-face of the rail 0, while the balls 0 are held in place againstthe bearing side of the rail by means of shoulders cl and 6, made by theinner downward and inwardly turn of the work-seat E and theoutward-projecting edge of the rail 0, which form an independent upperand lower receptacle. However, the upper receptacle may be dispensedwith, if desired, as the balls of the lower recepta cle could be adaptedfor all purposes. Each workseat, with its respective jaw orclamping-back, is cast, preferably, in one piece and of the entirelength of the rail, as particu larly shown in Fig. 1 and partiallyinFig. 3. In this manner better adjustment of the doorframe can beobtained. It is apparent that the antifriction-balls may be placed uponthe bearing-face of either rails B or 0. However, it is preferable toconstruct only one longitudinally-adjustable work-seat in the mannerpreviously described. The work-seats are to similar parts gles, if theyshould not be properly set.

We have illustrated in Figs. 4 to8 and 9 to provided also with downwardprojections f, lapping outwardly their respective rail .to prevent themfrom shifting out when once in position, and the jaws or clamping-backsF F are provided with a series of ribs 9 to reinforce them.

To carry out successfully our invention, the various parts composing thedoor-frame are first properly assembled together by hand or otheraccurate means and placed upon the work-seats E and E, and while therail 0 is forced forward by means of the worm-screws D the adjustablework-seat E will move laterally toward the least resistance, if any, andcarry that side of the frame with it, while the other side remainsstationary upon the work -seat E. Thus by this method the rails andstyles can be adjusted at right an- 12 two different forms ofconstructing our invention and the one already described, and it will bereadily seen while glancing over the drawings that our improvements canbe quickly adapted to existing clamping machines without the slightestalteration by providing upon one of the work-seats two horizontal angleplates G and H, projecting parallel'to the usual jaw or clamping-back ofthe work-seat proper, and antifriction balls or rollers :placed betweenthe plates. Thus in this mannerwehave provided an ordinary machine withan adjustable work-seat. How ev'er,w'hile remodeling an old machine orconstructing a new one the work -seats proper may be substituted withbetter advantage by series of brackets E havingrectangular outward-projecting back Fi provided with the 5 usual rib g, and may be heldinposition upon the "rails B and O by means of downward project-ions flapping the rails. These brackets are particularly shown in the drawingsfrom Figs. -4 to '12, while the two horizontal angle-plates G and Happear only in Figs. 4

to 8, where it will be seen that plateG is horizontally mounted upon oneseries of brackets and rests'against theiriectangular projectingba'cks,and the-plate H is supported upon plate I G by means of balls h,seated in asuit-able groove out upon the meeting faces of the two 1plates.

its rectangular back forms the jaw or clamp-' ing-backpreviouslydescribed. To carry out our object successfully, it is preferable topermanently secure the plate G upon the brackets and to .provide plate Hwith proper means or guides to prevent the same from In Figs. 7 and 8 wehave Thus in this manner the plate H becomes the adjustable work-seatproper, while smooth surface can be had upon the outer side of therectangular back of plate H.

Figs. 9 to 12 illustrate a third form of constructing the work-seats,which consists in placing horizontally upon the brackets, previouslydescribed, a stationary board or plate L, upon which a horizontalstationary bar J is mounted and rests against the projecting backs ofthe brackets. Upon the board L and placed parallel to the stationary bar.I is a horizontal movable bar K, held in position by means ofantifriction-rollers Z, placed vertically between the meeting sides ofthe bars. Thus'arranged the bar K constitutes substantially ouradjustable clamping-back while in operation. The-rollers Z justdescribed may be substituted, if desired, by balls Z, seated in groovesout upon the meetingsides of the bars, as shown in Fig. 12.- In thiscase the board L may be dispensed with and the bar K maybe held inposition by means of locking-plate M, secured or otherwise bolted to thebrackets.

It will be readily perceived from the above description and reference tothe drawings annexed that our improvements could be used for clampingbox-stu ffs as well as door-frames by-simply doubling at a right angleour stationary and moving clamping-jaws, which can be operated in themanner and by the means previously described.

Believing we haveproduced a convenient and ever-ready means by-whichdoors, sashes, blinds, 850., can be adjustably set, while clamping thesame,and having described fully our invention, what we'claim as new, anddesire to secure by United States Letters Patcut, is-
